Refactoring for Architecture Smells: An Introduction

“Cities grow, cities evolve, cities have parts that simply die while other parts flourish; each city has to be renewed in order to meet the needs of its populace… Software-intensive systems are like that.” – Grady Booch “Code smells” or “bad smells” [1] are considered structures or code fragments that […]

Evolution of MonoDevelop Structure

In this case study article, we analyze MonoDevelop IDE using Designite tool. We present how the structure and smell profile evolved (during 2011 to 2015 timeframe) with the help of a few graphs. By reading this article, you will know how you can perform a grounded analysis of the evolution […]

Is Refactoring a “Needless Rework”?
